Exhaust Sound

I am going to be putting on a magnaflow high flow cat and pacesetter headers within the next week. I currently have a magnaflow catback on my 2003 cavalier. My question is will the headers and cat change the sound of my car at all, or just make it louder? Also, does anyone have any personal experience good or bad with the pacesetter ceramic coated headers. Thanks.

Yeah, they will make your car sound different. The high flow cat will probably make it louder and the head makes it just sound different, you know? My friend got a header on his Del Sol and it sounded better, you just couldnt put your finger on why. Pacesetter makes good shit.
